Yes. But if you are doing via implementing/fixing/expanding vpa,
please do this in the symbolic package where it belongs. Do not import
it from symbolic into multi-precision package, so that later, needs to
be moved into the symbolic package again. Just do it on the symbolic
package.

As I said, if reports are to be trusted, nothing else aside vpa works
in the symbolic package. So remove the everything else from symbolic.
